TECHNICAL FIELD

[0001] The present invention relates to a grip for catching a ball, and particularly, to a grip for catching a ball which is able to catch a rubber ball having smooth surface and a baseball as well as a nappy ball.

BACKGROUND ART

[0002] Generally, a catch ball is a game tool by which people of two or more catch a ball thrown by the other people with a certain distance in a playground or in an empty space.

[0003] The catch ball is generally known as an adhesive catch ball which has an adhesive drapery on a front part of a catching plate having a handle so that a nappy ball such as a tennis ball.

[0004] The catch ball described as above, however, cannot catch a ball having smooth surface such as a rubber ball and a baseball. In addition, if the adhesive drapery is worn, even the nappy ball is not stuck strongly, whereby the life span of catch ball is shortened and interest for the catch ball is lost.

[0005] Accordingly, the present applicant designed a covering ball type grip for catching a ball and filed on Sep. 9^(th), 1998 (utility model application number 1998-17122, referred to as ‘first application’) and on Jan. 23^(rd), 1999 (utility model application number 1999-00878, referred to as ‘second application’) in Korea Industrial Property Office(KIPO), in addition, the first application is issued as utility model No. 205076 on Sep. 20^(th), 2000.

[0006] However, the design of the ‘first application’ is constructed such that the operation lever for opening ball-catching pocket is installed inside the handle and the user is able to open the pocket by pulling the operation lever with the handle. Therefore it has the advantage that the ball is able to caught using one hand, but the user needs much power in order to open the pocket.

[0007] In addition, the design of the ‘second application’ is constructed such that a separate pulling member is coupled to the ball-catching pocket, and the user holds the handle with one hand and pulls the pulling member with the other hand, whereby the ball-catching pocket is opened. Therefore, it is somewhat inconvenient because the user should use both hands in order to open the ball-catching pocket.

TECHNICAL GIST OF THE PESENT INVENTION

[0008] Therefore, an object of the present invention is to provide a grip for catching a ball having both ball-catching pockets which are opened easily by holding the handle with one hand and pulling one ball-catching pocket by the other hand, and preventing the ball from rushing out of the ball-catching pocket when the user catches the ball, whereby the reliability of the operation is able to be increased.

[0049]FIG. 5 is a transverse cross-sectional view showing operation state of the pocket interworking unit when the ball-catching pockets are unfolded. As shown therein, the pair of interworking gears 45 and 45′ rotate simultaneously with the ball-catching pockets 20 and 20′, coupled by the fear coupling units 23 and 23′. Thereby, when a user rotates one ball-catching pocket 20, then the other ball-catching pocket 20′ is rotated to the opposite direction by the pair of interworking gears 45 and 45′. Then the pair of ball-catching pockets 20 and 20′ are unfolded to both direction so that the user is able to catch the ball easily.

[0050] And, FIGS. 6 and 7 are showing the operation structure of the operation plate according to the present invention. FIG. 6A is a longitudinal sectional view showing the coupled state of the operation plate and the ball-catching pockets when the ball-catching pockets are closed, and FIG. 6B is a cross-sectional view of line D-D in FIG. 6A. Also, FIG. 7A is a longitudinal sectional view showing the coupled state of the operation plate and the ball-catching pockets when the ball-catching pockets are unfolded, and FIG. 7B is a cross-sectional view of line E-E in FIG. 7A.

[0051] The operation plate 50 maintains the unfolded state of the ball-catching pockets 20 and 20′ in front of the frame 10, and at the same time, has a function of releasing the unfolded state of the ball-catching pockets 20 and 20′ when a thrown ball is bumped therein.

[0052] That is, lower back part of the operation plate 50 is connected to the frame 10 by a hinge groove 52 and is stood in vertical direction along with the frame 10 so as to be rotated frontward/backward directions. And a pair of restriction protrusions 51 and 51′ are formed on front lower part of the operation plate 50 in order to restrict the rotation of the ball-catching pockets 20 and 20′ to the direction of closing by the pocket springs 30 and 30′, when the pair of the ball-catching pockets 20 and 20′ are unfolded.

[0053] In addition, on the ball-catching pockets 20 and 20′, protrusion insertion recesses 24 and 24′ are formed on upper part of the hinge holes 21 c and 21 c′ corresponding to the restriction protrusions 51 and 51′.

[0054] The restriction protrusions 51 and 51′ and the protrusion insertion recesses 24 and 24′ are formed as square shape so that the restriction protrusions 51 and 51′ are inserted into the protrusion insertion recesses 24 and 24′, whereby the rotation of the ball-catching pockets is restricted only in the state that the ball-catching pockets 20 and 20′ are totally unfolded, as shown in FIGS. 6B and 7B.

[0055] That is, the restriction protrusions 51 and 51′, and the corresponding 5 the protrusion insertion recesses 24 and 24′ are formed as squared shape corresponding with each other, and embossed edges of the restriction protrusions 51 and 51′ are hooked on the engraved edges of the protrusion insertion recesses 24 and 24′, whereby the rotation of the pocket frames 21 and 21′, that is, the rotation of the ball-catching pockets 20 and 20′ is restricted.

[0056] In addition, an operation plate spring 55 for supplying the elastic force to the restriction protrusions 51 and 51′ so that the protrusions 51 and 51′ can be inserted into the protrusion insertion recesses 24 and 24′ when the ball-catching pockets 20 and 20′ are totally unfolded is installed between the operation plate 50 and the frame 10. And a spring fixing frame 53 in which the operation plate spring 55 is inserted and installed is formed on rear center part of the operation plate 50.

[0057] Therefore, as shown in FIG. 6, the restriction protrusions 51 and 51′ are crossed with the protrusion insertion recesses 24 and 24′ in the state that the ball-catching pockets 20 and 20′ is closed, whereby the restriction protrusions 51 and 51′ can not be inserted into the recesses 24 and 24′.

[0058] However, as shown in FIG. 7, when the ball-catching pockets 20 and 20′ are unfolded, the restriction protrusions 51 and 51′ of the operation plate 50 are accorded with the protrusion insertion recesses 24 and 24′ and inserted into the protrusion insertion recesses 24 and 24′. At that time, the operation plate 50 is slanted frontward by the elastic force of the operation plate spring 55, then the restriction protrusions 51 and 51′ are inserted into the protrusion insertion recesses 24 and 24′, whereby the rotation of the ball-catching pockets 20 and 20′ to the direction of closing is restricted.

[0059] In the above state, when the ball is bumped on the operation plate 50, the operation plate 50 rotates centering around the hinge groove 52 and then the restriction protrusions 51 and 51′ are seceded from the protrusion insertion recesses 24 and 24′. At that time, the ball-catching pockets 20 and 20′ are closed by the elastic force of the pocket springs 30 and 30′, and are able to catch the ball.

[0060]FIG. 8 is showing the operation plate of the grip for catching a ball according to the present invention. FIG. 8A is a plan view of the operation plate, FIG. 8B is a front view, and FIG. 8C is a side view.

[0061] The operation plate 50 according to the present invention has slopped surfaces 50 a and 50 b so that the ball,is not bounded toward, but bounded inward of the ball-catching pockets 20 and 20′. And the slopped surfaces 50 a and 50 b are formed long in the vertical direction and are located facing the both ball-catching pockets 20 and 20′ respectively.

[0062] In the operation plate 50 having the slopped surfaces 50 a and 50 b, a highest line 50 c highest from the bottom surface of the operation plate 50 is located eccentric to one side, whereby one slopped surface 50 a is formed to have larger area than the other slopped surface 50 b. In addition, the slopped surfaces 50 a and 50 b are formed as convexed round shape.

[0063] Also, the operation plate 50 has the thickness of upper part h1 smaller than that of lower part h2 so that the operation plate is formed slopped to the upper direction, as shown in FIG. 8C.

[0064] As described above, the operation plate 50 has the highest line 50 c eccentric to one side, and therefore the center part of the operation plate 50, where the ball is likely to bumped, is formed as a slopped surface 50 a, whereby the bounces of the ball out of the ball-catching pockets 20 and 20′ is able to be reduced. In addition, the thickness of the upper part h1 is formed smaller than that of the lower part h2, whereby the thrown ball describing parabola is easily caught.

[0065] The operation of the grip for catching a ball according to the present invention will be described as follows.

[0066] As shown in FIG. 5, when the user holds the handle1 with one hand and pulls the pocket frame 21 of the one ball-catching pocket 20 with the other hand, the interworking gear 45 coupled to the pocket frame 21 is rotated to one direction, then the other interworking gear 45′ meshed with the interworking gear 45 is simultaneously rotated to the opposite direction.

[0067] At that time, the ball-catching pocket 20′ including the other pocket frame 21′ coupled to the other interworking gear 45′ is rotated to the opposite direction of the rotation direction of the ball-catching pocket 20, whereby the two ball-catching pockets 20 and 20′ are totally unfolded in a certain range while compressing the pocket springs 30 and 30′ in FIG. 4A.

[0068] Herein, as shown in FIG. 7, the operation plate 50 located between the two ball-catching pockets 20 and 20′ has a force to rotate frontward by the operation plate spring 55. And when the both pocket frames 21 and 21′ are unfolded, the restriction protrusions 51 and 51′ of the operation plate 50 are inserted into the protrusion insertion recesses 24 and 24′ of the pocket frames 21 and 21′, and then holds the pocket frames 21 and 21′. Thereby, the two ball-catching pockets 20 and 20′ are totally unfolded.

[0069] After that, when a ball thrown by the other person is bumped on the operation plate 50 between the ball-catching pockets 20 and 20′ in the state that the user is holding the handle 1, the operation plate 50 is rotated by being pushed to backward centering around the hinge groove 52 while compressing the operation plate spring 55. At that time, the restriction protrusions 51 and 5′ of the operation plate 50 are seceded from the protrusion insertion recesses 24 and 24′ of the respective pocket frames 21 and 21′, and accordingly, the ball-catching pockets 20 and 20′ are put together by the restoring force of the pocket springs 30 and 30′, whereby the ball is able to be caught.
